HOISTING AN-D CONVEYING. DEVICE.

Specification of Letters Patent.

To all whom it may concern.-

Be it known that I, JOSEPH I-I. DICKINSON, of Atlanta, in the county ofFulton and State of Georgia, have invented a new and useful Improvementin Hoisting and Conveying Devices, of which the following is a full,clear,

' and exact description.

' way My 'nvention relates to improvements in cableways, ropeways,andsnmlar classes of hoisting and conveying devices in which a IReferenceis to be had tothe-drawings accompanying herewith and forming apart of this sp ecification, in which the same reference charactersindicate corresponding parts in the different figures. 1

Figure 1 is a diagrammatic side elevation of a cableway containing myimprovements.

- Fig. 2 is a side elevation of a carriage, illustrating one form of myinvention. Fig. 3 is w an edge view of the carriage shown in Fig. 2.

Fig. 4 is a side elevation of a carriage, illustrating another form ormodification of ,my

invention, and Fig. 5 is an edge .view, of the carria e shown in Fig. 4.

In t e operation ,of cableway hoisting and conveying devices employing atraveling carriage and ahoisting-rope it is generally necessaryto eitherweight the fall-block to insure its descent or employ fall-rope carriersto support that portion of the hoisting-rope extending fromthecarriagetoward the engine or other-means by which the hoisting-ropeis operated.

One object ofmy present invention is to rovide means by which thedescent of the all-block may be insured irrespective of its weight orthe length of the unsupported portion of the hoisting-rope next to thecarriage.

In Fig. 1 I' have shown my device as applied to an ordinary cableway. Arepresents the supporting or trackway cable, which is supported at a a,res ectively, from the head and tail supports. pon this trackway-cable Aruns the carriage C by means of wheels I..

An endless hauling-rope B is attached by its ends to the carriage andextends over guides,

as the pulleys 8, 9, 5', and 3, to a drum G by which it is actuated andthe carriage caused to travel along the trackway.

A hoisting-rope H extends from a drum G over a guide-pu ey 1 to thecarriage, assing over the pulley P and then down an about the pulley ofthe fall-block F and u to the carriage, to which its end is secure ThePatented Dec. 5, 1905.

section of the hoisting-rope next to the car-- a riage is replaced by achain h, and the wheel p is made a pocketed or chain wheel, so that pthe chain has a positive grip thereon.

Mounted in the carria e is a second chain or pocketed wheel T, anconnected to turn therewith is a gear-wheel t.

nected to turn with the chain-wheel 'P, so that if one of thechain-wheels is turned th other must turn with it.

An endless'rope extends from a drum G, as the two runs D and D, overguide-pulleys 2 and 4 on the head-support and guide-pulleys 6 and 7 onthe tail-support. The two runs of this rope, which I call alowering-rope, are

supported, respectively, on pulleys K and T on the carriage. The pulleyT, aspreviously explained, is a chain-wheel and is connected with thechain-wheel P, over which the hoisting-r'ope passes. That run D of thelowering-rope which passes over the wheel T has a chain-section dtherein adapted when it en- This gear-wheel meshes with a gear-wheel p,which is congages the wheel T to turn said wheel and to thereby turn thewheel P, so that it is possible by manipulating the ropeD to. assist inlowering the fall-block andthe paying .out 'of the hoisting-rope.

I am aware of the Dusedau Patent, No. 566,849, dated September 1, 1896,in which is described a trackway, a hoist mounted on a load-carriage, arun of hoisting-rope extending from the carriage to one end of thetrackway, and a run of lowering-rope extending from the carriage to theother end of the track-' way, said runs constituting parts of an endlessrope operated by a single drum at the engine. In my construction thereare two runs of rope extending from the hoist on the carriage to thesame end ofthetrackwaynamely, a run of the rope D and the run of therope H. In my construction also the lowering is effected by. hauling inthe run of rope ('i. 6., that run of rope D between the carriage and thehead-support) which extends from the carriage to the same end ofthetrackway with the hoisting-rope. In my construction also these tworuns of rope extend'to separate drums of the engine, so as to becapable'of hauling in in unison as the carriage approaches the head or payingout in unison as the carriage recedes from the head or hauling in andpaying out inversely in hoisting or lowering while the carriage, is heldstationary by the traction-rope B.

A suitable three-rope drum-engine for the three drums G G G being knownto those skilled in the art, a description or representation of it isunnecessary.

I do not wish to limit myself to the employ ment of chains orchain-wheels in the hoist as a means-of gripping, and in many otherrespects features may be omitted or changed without departing from theprinciple of my invention.

Having thus described my invention,what I claim as new, and desire tosecure by Letters Patent, is

1. The combination with a carriage for cableways and similar conveyingdevice having two wheels therein connected to turn together, of ahoisting and a lowering rope adapted each to engage one of said wheelsand extending from the carriage to the headsupport.

2. In a cableway or similar conveying device the combination with atrackway, a car riage adapted to run thereon, and a haulingropeconnected with said carriage to move it, of a hoisting-rope extendingfrom the carriage to one end of the cableway, a loweringrope extendingpast the carriage, two Wheels upon the carriage adapted to respectivelyengage said hoisting-rope and the lowering-rope to turn therewith, saidwheels being conneeted to turn together.

3. In a cableway the combination with a trackway, a carriage thereon, ahauling-rope and a hoisting-rope extending from the carriage to one endof the cableway, of a lowering-rope extending past the carriage, twowheels connected to turn together and adapted respectively to actuatethe hoisting-rope and to be actuated by the lowering-rope.

4. In a cableway the combination with a trackway, a carriage thereon, ahauling-rope and a hoisting-rope extending to the headsupport, of aloweringrope, two wheels upon the carriage connected to turn togetherand provided with means for positively engaging one with thehoisting-rope and the other with the lowering-rope, whereby thehoistingrope may be positively lowered from the carriage.

5. In a cableway the combination with a trackway, a carriage adapted torun on said trackway and having two wheels connected to turn togetherand adapted to receive respectively the hoisting and the lowering rope,of a hauling-drum, a hauling-rope connecting the hauling-drum and thecarriage to move it, a hoisting-drum, a hoisting-rope extending from thehoisting-drum to the carriage and over one of said connected wheels onthe carriage, a lowering-drum, and a lowering-rope extending from saiddrum to the carriage and. engaging the other of said connected wheels onthe carriage.

6. The combination with a tracluvay, and a carriage adapted to travelthereon, of a hoisting drum, a hoisting rope extending from said drum tothe carriage, a loweringdrum, a lowering-rope extending from its drum tothe carriage, and two connected wheels adapted one to receive thehoistingrope and the other to receive the loweringrope.

7. A hoisting device comprising two wheels connected to turn together, ahoisting-rope extending from a distance to and about one of said wheelsand a lowering-rope extending from a distance to and about the other ofsaid wheels, whereby the outer end of the hoisting-rope may be caused todescend by pulling upon the lowering-rope.

8. In a hoisting and conveying device the combination with a trackway, acarriage adapted to travel on the trackway, a haulingrope connected withthe carriage and a hoisting-rope extending from the carriage to one endof the trackway, of a lowering-rope, and two connected wheels upon thecarriage adapted one to receive the hoisting-rope and the other toreceive the lowering-rope, said ropes and wheels having drivingengagement With each other.

9. In a hoisting device the combination with a hoisting-rope, a hoistlowering-rope, of separate sheaves for said ropes, a driving connectionbetween said sheaves, and means independent thereof for raising thehoistingrope.

10. In a hoisting apparatus, in combination, a sheave at the top of thefall and a hoisting-rope extending over said sheave and containing twosections of different capacities for engagement; one of said sectionsforming a clutching engagement with said sheave and the other not.

11. In an apparatus of the class described a trolley and an endlesshoist-operating cable therefor in rope-supporting engagement with thesaid trolley with both its outgoing and return strands.

12. In an apparatus of the class described a trolley and an endlessoperating-cable therefor in rope-supporting engagement with the trolleyat substantially equal distances on either side of the longitudinalcenter thereof.

In testimony whereof I have hereunto affixed my signature, in thepresence of two witnesses, this 18th day of January, 1902.
